These two members are theninclosed in a sheet of insulating material 6, whichmay be wrapped around the same, or therewith, in lhe'jmafi'ner'hereinbefo'r "described, wh ch insulating"n'iat'erial is pre erably-"of'l'iarwlfin. paper of suiiieient size to cover the line, since it is'not necessary to wrap it over the blotting paper. The structure or cell thus made may then be inserted in a carton, but preferably inclosed within a suitable wrapper 7, which may be. in the manner hereinbefore described wra ped around the cylinder so made up. of the sheets making up the battery may, however, .be

The cylinder may then be filled by resting one end on a suitable latform or table', but preferably one end is provided .with aelosnrei), which may be'in the form' of I, -;the end may be'pitched to formfa Bob for the" cylinder?
